Introduction
Overview
The Sealevel Systems ULTRA-COMM+2.LPCI is a two channel Low Profile PCI serial I/O adapter for the PC
and compatibles. It provides two field selectable RS-232/422/485 serial ports supporting data rates up to 921.6K
bps.
Configure both ports as RS-232 for standard serial COM: port requirements. Choose the RS-422 mode for long
distance device connections up to 4000ft. where noise immunity and high data integrity are essential. Select RS-485
and capture data from multiple peripherals in a RS-485 multidrop network. Up to 31 RS-485 devices can be
connected to each port to automate your data collection. You can even mix the ports in any of the interface
combinations to provide maximum flexibility to your application.
In both RS-232 and RS-422 modes, the card works seamlessly with the standard operating system serial driver. In
RS-485 mode, our special auto-enable feature allows the RS-485 ports to be viewed by the operating system as a
COM: port. This allows the standard COM: driver to be utilized for RS-485 communications. Our on-board
hardware automatically handles the RS-485 driver enable. UART upgrades are available providing 32,64 and 128
byte FIFOs.
The ULTRA-COMM+2.LPCI ships with a Low Profile PCI bracket that will only work in a Low Profile PCI slot.
If you need a standard size PCI bracket, please order Item# 7205S.
